O.I. Analytical

OI 3090 AS

We distribute O.I. Analytical TOC's with the following features:

  • For Drinking Water and Wastewater Applications
  • Available in EPA, Standard Methods approved Heated Persulphate mode or EPA, MISA and Environment Canada approved combustion mode selectable from 680°C to 950°C or the 1030D TOC that features both perulphate and combustion TOC modes on the same instruments.
  • Meets USP TOC and FDA/Health Canada Cleaning Validation Requirements
  • Windows™ Based Software for fully Programmable Control and Data Acquisition in Manual or Automated Modes
  • Single or Multi-Point Calibration Format
  • Solids and On-Line Process TOC Analyzers also available


OI Analytical continually strives to provide high-quality, precision instruments for TOC analysis. Whether you need the high-temperature persulfate oxidation method for precise, low-ppb results, using:

  • Wide operational range (2 ppb–30,000 ppm)
  • Supports TC/TIC/TOC/NPOC analysis techniques and standard measurements
  • Parallel reaction chamber option available for high-throughput concurrent sample processing
  • Upgradable allowing performance of combustion and wet heated persulfate TOC analysis techniques on a single instrument

Laboratory and at-line configurations available for process monitoring or powerful catalytic combustion technology for salty or dirty samples, using:

  • Wide operational range, 100 ppb C to 30,000 ppm C
  • Supports TC/TIC/TOC/NPOC analysis techniques and standard measurements
  • Advanced ACT II combustion reactor technology (patent pending) enhances performance, extends catalyst life, and reduces maintenance
  • Optional analysis module for total nitrogen (TNb)
  • Upgradable to a platform capable of performing both combustion and wet heated persulfate TOC analysis techniques

OI Analytical's TOC analyzers are big on performance. Add the extra capabilities of an Autosampler to automate your analysis or add a stand-alone Solids TOC Analyzer to analyze solids, sludges, and slurries. With outstanding accuracy, easy use, and reliability, OI Analytical TOC analyzers are the preferred choice for your TOC measurement needs.


OI Automated SFA-FIA-CN Analyzers

FS 3100

The Flow Solution™ FS 3100 Automated Chemistry Analyzer is a modular system for performing continuous flow analysis methods on water samples, soil, or plant extracts and digests using FIA or SFA techniques. The FS 3100 consists of an X-Y-Z autosampler (90 or 360 position), multi-channel precision pump, electrically-actuated sample injection valve, VersaChem Multi-Test Manifold™, and Expanded Range™ photometric or amperometric detector.

The FS 3100 supports two channels for FIA methods and three channels for SFA methods, minimizing the time involved in changing chemistries for different analytes.

FSCN 3100

The CNSolution™ Cyanide Analyzer is a compact, modular system for performing flow injection cyanide analysis on drinking water samples and wastewater samples from mining, metal plating, and other industrial operations. The CNSolution consists of a 90-position random access X-Y-Z autosampler, a multi-channel precision pump, an electrically-actuated sample injection valve, a VersaChem reaction manifold, and an amperometric detector.

The CNSolution measures available cyanide by a ligand-exchange, gas diffusion technique coupled with high sensitivity amperometric detection in accordance with USEPA method OIA-1677 and ASTM D6888-04.

An optional in-line UV Digestion module allows total cyanide analysis to be performed without a separate distillation step, reducing analysis time from hours to minutes.

The CNSolution can be equipped with a photometric detector for laboratories measuring total cyanide in post-distillation samples by USEPA method 335.4. This configuration can be supplied with a Midi-distillation system for simultaneous distillation of up to 10 samples.
